AT-OC9XML Dual Moving Coil Cartridge with Microline Stylus on Boron cantilever
Note: This OC9XML replaces the AT Cartridge AT-OC9/II which has just ceased manufacture. It is still available at £399 (or offers!) if you want the same performance and can live without the new body style. See

The AT-OC9XML Dual Moving Coil cartridge with Microlinear stylus is designed to provide outstanding channel separation. The Pure Copper by Ohno Continuous Casting (PCOCC) coils ensure pure audio transmission and are aligned in a reverse V-shaped formation to exert less pressure on the stylus, thereby minimizing distortion. Audio quality is further enhanced by a rigid aluminum body that reduces resonance, a neodymium magnet and premium permendur yoke that increase the magnetic energy, and the nude Microlinear stylus on a boron cantilever that tracks the record groove with incredible accuracy, low distortion and high-transient response. The cartridge body has been pre-threaded, enabling it to be mounted to a headshell or integral tonearm with just two screws – no nuts required.
